In the recent InDesign versions, the Justification alternates feature is completely failing in OpenType fonts
In the recent InDesign versions Adobe has introduced HarfBuzz as the default text shaping engine but the Justification alternates feature is now not working in OpenType fonts at all, we have confirmed it by testing Arabic fonts. For Adobe text rendering engine this feature still works seamlessly but for Harfbuzz this fails silently. Is there some compatibility issue of Harfbuzz with Adobe paragraph model or we are missing something as we have tested several fonts with same result?
It has disturbed all our past documents as the users use this feature in the whole documents to beautifully justify the paragraphs using justification alternates.
